(Area and perimeter of an equilateral triangle) Write a program that displays the area and perimeter of an equilateral triangle that has its three sides as 9.2, using the following formula: area = 1.732 * (side)²/ 4 perimeter = 3 * side #Beginner In gcc c++ compiler using namespace std; #include <iostream> using namespace std; int main() { float side = 9.2; float area = 1.732 * side * side / 4; float perimeter = 3 * side; cout << "area of the triangle is : " << area << endl; cout << "perimeter of triangle is : " << perimeter; return 0; } copy Output area of the triangle is : 36.6491 perimeter of triangle is : 27.6 [Program finished] Need of Programmer Need of Programmer
Body Mass Index (BMI) is a measure of health based on height and weight. You can calculate your BMI by taking your weight in kilograms and dividing it by the square of your height in meters. The interpretation of BMI for people 20 years or older is as follows: BMI Interpretation BMI < 18.5 Underweight 18.5 <= BMI < 25.0 Normal 25.0 <= BMI < 30.0 Overweight 30.0 <= BMI Obese #include<iostream> using namespace std; int main() { //weight in kilograms float kilograms; //height in meters float meters; //enter the values cout<<" enter your weight in kilograms ";cin>>kilograms; cout<<" enter your height in meters ";cin>>meters; //calculate BMI //formula: weight in kilo / (height in meter)*(height in meter) float BMI = kilograms / (meters*meters); cout<<" your BMI is "<<BMI<<endl; if(BMI<18.5) { //BMI < 18.5 Underweight cout<<" you are under ...
(Slope of a line) Write a program that prompts the user to enter the coordinates of two points (x1, y1) and (x2, y2), and displays the slope of the line that connects the two points. The formula of the slope is (y2 - y1)/(x2 - x1). #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter the coordimnates for two points :\n" ; cout<< "x1 and y1 :" ; cin>>x1>>y1; cout<< "x2 and y2 :" ; cin>>x2>>y2; float slope; slope=(y2-y1)/(x2-x1); cout<< "The slope for te line that connects two points\n(" << "x1=" <<x1<< ",y1=" <<y1 << ",x2=" <<x2<< ",y2=" <<y2 << ") is " <<slope; return 0; } copy Output Enter the coordimnates for two points : x1 and y1 :1 2 x2 and y2 :7 5 The slope fo...
